混凝破碎动力学模型

A kinetic model for coagulation-fragmentation

Damien Broizat

摘要:

本文的目的是证明一个凝聚-破碎动力学模型的存在性定理,其中初始数据满足自然物理界,假设粒子数有限,$L^p$ -范数有限.由于缺乏\textit{a priori}估计,我们使用迪佩纳和狮子介绍的重整化解决方案的概念。证明是基于弱紧性方法在$L^1$,允许$L^p$ -范数传播。

英文摘要:

The aim of this paper is to show an existence theorem for a kinetic model of coagulation-fragmentation with initial data satisfying the natural physical bounds, and assumptions of finite number of particles and finite $L^p$-norm. We use the notion of renormalized solutions introduced dy DiPerna and Lions, because of the lack of \textit{a priori} estimates. The proof is based on weak-compactness methods in $L^1$, allowed by $L^p$-norms propagation.
